British business exploit Malayan economic resources. Malaya possessed valuable minerals such as coal, bauxite, tungsten, gold, iron ore, manganese, and, above all, rubber and tin. A Colonial Office report from 1950 noted that Malaya’s rubber and tin mining industries were the biggest dollar earners in the British Commonwealth. Rubber accounted for 75 per cent, and tin 12-15 per cent, of Malaya’s income.

‘Invading from the north, the Japanese rapidly overran Malaya and took Singapore in 1942. After the war, in 1948, a Federation of Malaya was created under British protection, but British and Commonwealth troops had to put down a Communist insurrection, which lasted into the early 1950s. It was by now agreed that Malayan independence was the answer to the Communist claim that they were fighting to free the Malayan people from the British yoke. An election in 1955 was won hands-down by the United Malay National Organisation (UMNO) by running Malay candidates in Malay-dominated areas, Chinese candidates in Chinese areas and Indian candidates in Indian ones. The UMNO’s leader Tunku Abdul Rahman became prime minister when the independent Federation of Malaya came into being in 1957. ‘
